guy at work has a fifth wheel camper, looked into going up to Bar Harbor, ME area $900 for five nights, you could get a hotel for that and not have to drag it there and back. His buddy has a fifth wheel also his truck gets 6 MPG while towing!

My car gets 28-30 with my a little to tall TD, the guy I work with gets 16 towing or not with diesel. (he has an hour drive to work like me)`
My TD is my bed two nights a week at work, it really isn't any different than the free room I had for years.
Oh the guy at work is heading way up into NH mountains instead, $90/night for full hookups.
The big trailers that make sense around here are the ones that spend the season at campgrounds along the beaches. My dad got a small house on 1/8 acre along York Beach, ME for 89K back in '95, last valuation was for 360K , a couple grand a season for a camper site, and a twice a season U-haul rental to drag the RV to and from the campground is the only way I could afford anything similar. Of course that would be the only place I would go all year, the TD will let us head plenty of other places.
